Pelleting is a mechanical process of compressing ground raw materials into solid cylindrical granules — pellets. Used for biomass, animal feed and fertilisers.
Pelleting is a process in which pre-ground and dried raw material is fed into the pellet mill chamber, where a roller mechanically forces it through the die holes. Under the pressure and heat generated by friction, lignin in the raw material is activated and acts as a natural binder — the pellet gains hardness without any additives.
The finished pellets are cut by knives to the desired length, then pass through a cooler which hardens them and reduces moisture to ≤10%. The finished product has high energy density and is easy to transport and store.
Drying to ≤15% moisture, crushing to a fraction ≤6 mm
The roller presses the raw material through the die under 100–250 bar pressure
Cooler reduces pellet temperature and moisture to ≤10%
Vibro sieve separates fines; pellets are packed in bags or in bulk
Pelleting is applied in a large number of industries — wherever loose or wet material needs to be transformed into uniform granules.
